To all. 1071/0111.. t may concern? A Be -it known that We, HENRY WLNN,ofMalden, in the county of Middlesex, and CHES- TER M. SPALDING, ofBoston, in the county of Suffolk, State of Massachusetts, have iniCounting-Registers, whereof the following is a specication. i

The object of this invention is to secure various advantagesincounting-registers, es` pecially to make one easy to work, which cannotmake a mistake, in which when .locked the count cannot be tampered-with,in which when a count is shown the operator can instantly wipe out thecount,- restoring the operative parts to the position requiredto beginthe count anew, to make a register operative without springs and usefulin caleulat in g-1n achines, and toshow results, carry tens, and combinewith other mechanism for I neycha'nical calculations. Ease of operationis secured by the use of simple gears, most orall of which are nottouched by any spring when operated to count. Accuracy is' secured bygearing together the Iregister-wheels in such manner that amistakeleannot occur without breaking the register, while in commonregisters 'the wheels are usually turned by spring teeth or pawls whichare occasionally'throivn over their notches without operati-ng theregistcr, calming mistakes. Instantaneous restoration of thopelativeparts from any position 1o the posirieu required to start the count anewis secured by disconnecting the' register-wheelsfroin their continuousgearing, connectinga tooth which may be rotated by the operator with aprojection on each registerwheel to be restored, and thereby-rotatingsuch 'register-wheel back to its starting position, while theintermediate gears remaining connected with the register-wheels andbeing allowed to remain meshed with each other are necessarily rotatedback 4to their starting position as the, registerfwheel is moved back toits own.

In the latter depressionsof the periphery of each registerwheel in the register shown areengraved or lotherwise shown the nine cardinal numbers with the zero inconsecutive order, as indicated in Figs. l and 6. The drivertoothop-Verating in one notch only of the register-wheel at each rotation of thedriver rotates the former one-tenth of a rotation byeach rotation,

and rotate with any part of which the rota-.p

' tions are to be counted, rotates the registerwheel only one-tenth of arotation to each of its own rotations, moving it with its own speed whenmoving it at all and locking it stationary, so that a count may beobserved u'pon it till another count is due, and since the cardinalnumbers with the zero appear in consecutive order in the ten eq'ualparts of the periphery of the register-wheel,`f the zerosection be takenas the starting-point or observation-section, the counts of thecontinuons rotations of the driver in one direction will appear at' theobservation-section (which does not change its'place) until the tenth roA highest place of'decimal notation, is an interm odiate gearwheel,located in positionA to mesh into a corresponding intermediate gearwheel on the opposite shaft, which latter gear is rigidly attached tothe driver of the register-wheel occupying the'next higher place indecimal notation. Thus to the register-wheel D, which is in ithe unitsplace, is'rigidly attached the intermediate gear F, which taires intothe intermediate gear G, rigidly attached to the driver E", whichoperates the register-'-A wheel in the tens place, so theinterniediategears F F2 F3 F4 F5 are respectively rigidly attached to theregister-wheelsrD' D3 D4 Ds4 and respectively take into correspondingintermediate gears G G2 G3 G4 G5, which are,

respectively rigidly attached to the'drivers E2 A A E3 E4 E5 E6, eachconnecti-ngpair of interme- Y' onerotating with its connectedregister-lV wheel and the other with the driver o 'tl-ythe next higherregister-wheel, Whichby its/Town vfull rotation rotates thatregister-wheel` one,-

tenth of'a rotation, it follows that each register-wheel'of a lowerdecimal place is geared to the register-wheel of the' nent higher deci'mal place in such manner tha-t onejrotation ofthe lower wheel causesone-tenth of -a ro,`

tation of the next higher, so if the units and the tens wheels startwith their zeros in an ob servation-line acorn plete rotation ofthe'nnitswheel bringing itfs'zero again to that line will throw up ltothe line on the tens-wheel, if the direction of the rotation be asindicated by the arrows, Fig. (5, and 'thus the tens of each wheel of alower decimal place are carried to the next higher and. theirrcountsleft there registered..

The intermediate gears may of course be of anyvariety or number whichwill accomplish this result, Vand various means may be suggested totransfer the rotation of the reg- .diate gears thus serving withadrivert-o gear'.-

ister-wheels to the drivers of the next higher wheels in place; but inthis case common spur-gears are used, and when they are used .it isbetter that the number of teeth of each shall be a mnltipleof tengsothat each notch IIC of each register-,wheeljshall-have thesame angularposition from shaft C as a center as every other relative to acorresponding tooth or notch on its intermediate gear. This will resultin placing the numbers always in a true line from' 'rightto left forobservation. Inthis register the driver of the units-wheel is rigidlyattached by the screw c to the shaft C',(see Figs. 2,2%,and 5,) rotatingwith itpvhile `all the other drivers, the'v registerwheels, and

intermediate gearfwheels Akrotate on their respective shafts.v Sointheo'peration of counting the shaft C'rotates `while the shaft C is d d2d3 d4 d5, while another loose washer d6,

acting inconjunction with the .vheel L'rigidly attached to shaft C'against the case,

sEsr AvAiLAsLE comI huidsthc .sf-:t ol drivers and attached inter-;iediatc gears, as Well as the shaft C', in their properplaces in thecase,although of course projections on the gear-wheels making each filla designated space would accomplish the same result, or the washersmight be rigidly attachedto shaft C' without changing -i heir elect, orthe shaft C' might be held in place in many ways, oneof which would beto make the external wheels shown attached to it to tit on the exteriorof the case. Was-hers e e' c2 e3 e4 e5 c6, similar to the former, butslit, as shown in Fig. 1l', to permit pins Io'pass longitudinally inthem, serve a like purpose to hold lthe register-wheels and theirattached intermediate gears in place.- They are not i essential,sincethe rims f the gears on shaft A C might abut and the case beprojected against the wheel D6 as against projection e7 of wheel D, asshown in Fig. 5, which projection also might be a washer.- Thesewashers,

-with pinfin shaft C,- prevent'side motion to the left in' thecase ofthe shaft C or the gears which it carries, while the tooth g of thepivoted lever H ente-rs -a cross slit or opening 7L in shaft C, as; seenin Fig. 3, and while there' holds it frominotion to the right, while thetootlrg itself issolidly held from such 1notion by the sides of the slotin the projection I outside of the c'ase, through which it passes whileits frontend is in the shaft, as well as by the screwj on which it ispivoted to the case.

Rigidly attached by screws'or otherwise to vthe shaft C is the spurgear-wheel J and the crank K, each of whichmay be used to conneetrotating parts or bysimple attachments reciprocating to be counted.

It heilig desirable that shaft C should rotate only in one direction forcounting, the common ball-ratchet. is introduced, with the two balls k7a.', located in chambers Z ZoT the case so shaped that thefriction onthem of the shaft rotating in the direction not desired Vtends to crampthe balls into aspacc loo narrow for them and stops the rotation; butrotation in the other direction, tending to drive them into aspacegiving them ample room, is not Ainterfered with. Obviously a commonspring-ratchet attached to the case and n orking on the wheel carryingdriver E would accomplish the same purpose,th'ough with more noise. Ifreverse rotation is desired foi-subparts ofwhich the motions aretractions from the count, the balls may b'e-removed.'

Through the Vcase is cut adjacent' to each of the register-wheels anobservation-opening, the openings m m2'm3 m4 beingshown, the seriesstanding longitudinally with shaft C.

Attached to driver Eis a segment-gear L, (see Fig.- 7,) used in drivingthe driver by a double rack to count reciprocating motions.

The case B may be made in4 parts, as desired, which may he rigidlyscrewed, riveted,

ororherwise fastened together.

The operation ot' the device for counting is as follows: Eachregister-wheel is arrau ged at starting with its driver in the positionof those parts seen in Fig. (i, the zero being brought to theobservation-opening and the drivertooth having the position there shownwhich .it has when it has justceased to move its register-Wheel and-the'driver has with its pe- 'rip'nery locked the wheel into place.Driver -E being so attached to the mechanism of which the motions are tobe counted astio be in thedre'ction indicated by the arrow on the driver seen in Eig'. driving its register-wheel 4in the reverse direction.Plainly the fi rst rotation of the driver E will bring the number l onthe wheel D tothe observation-opening; thesecond,thegure2; the third,3,'and so on, each rotation bringing there the rotation zero will returnthe`rc, A t'the same 'time the ten notations of the driver E have causedone rtatioh 'of-the driver E', at the end of which the ligure l ofthetens-wheel is brought to its observation-point, making the count showcorrectly 10, so the l y remains, registering the 'rst ten ,rotations of`d river E, while the additional ones are .shown inthe units-openingtill ten more rotations bring 2 to the tens observation-point and zeroto the units. showing the number 20, the correct count of the rotationsofthe driver E always appearing. In like way l will be added to thecount of the hundreds-wheel count reachin g 100. So 'the countproceeding the tens will be carried from the register-wheel in eachlower` decimal place to the one in the next higher and the true count ofthe rotations of the driver E will always appear in the line ofobservation -points'till 9,999,999, the limit ofthe register,'shall bereached, aft-ei which the parts will all assume their startingposition.. Subtractions -from the count. may be made,if the bells k 7s''be removed, by simply reversingthe rota tions of the driver E, when thecounts before shown will reappear in reverse order; but 'the registerwill rarely be required to count quired when any count is being shown tore` store'all the parts'to their-starting position for beginning anew,at'which in this register the iigI resin the ohservatiousectious showzero.y i lhis process is calledrestoratiom and s .n.is accomplished:

by such engagement said united register and intermediate wheels' and Theregisterwheel D". Space is made between each registerwheel and theintermediate wheel attached to .the next lower register-wheel bychambering out the Wheels adjacent to the placewhere space is`reguiredlto llocaia said wheel and s aft pinsandfperinit themV to`rotate in the ordinary use-ofthe register for counting withoutinterfering-with each other. Chambering ou't'lofoneorrhoththeadjacentwheels in this way pei-'mits fthe. l observation-points oftheregister-wheel toglie constructed: nearer together. I h shers e e e2 ese* e5 e6 have slits p p' p2 psptp pj permitting the shaft-pins to pass.longitudinally in them ;A but the slit-p6 -does not pass throughwashere6, its end affordi'ngastop against which-pin'n,6 abuts when theshaft-pinsv have.. beenVv carried far .enough longitudinally with theshaft Cto engage with -the'Wheel-pins, after'which pin fn, if the shaft`moves furtherl longitudinally,driv es the series ofregister andattached 'intermediate wheels with it and the shaft'in suchmotiou. Inthe shaft C is a spline consisting of a 'key M, working in aslot q ofthe 'projection I of the case. This key acting against thev sides of theslot prevents the' shaft C from rotating until it is passed out fromsaid slot q, and as the vtooth g prevents this 'passagefwhen theregister is used for counting this shaft does not rotate during thatprocess,' though such rotationiwould not interfere with the counting,nor is theprevention of thisrotation essential to :restoration to zero;'but itsadvantage consistsfchie'fly in keeping the shaft-pins at aproper starting-point, where they cannot strike the ends of thewheel-'pinswhen moving with the longitudinal motion of the shaftto'engage them, `said wheel-pins when the tooth of thefirstdriver E isnot in its notch having each only teniangular positions, counting fromthe shaft as a center, in which they can stand, and thestarting positionof each of.v the shaft-pins being arranged with reference ,to tbsepition's, so that the shaft-pins shall not imninge the ends of thewheel-pins when so moving to'engage them. To make sure that this toothof driver E shall not be in the notch of its register-wheel when theparts are'moved into position for restoration to zero is one ofthepurposes of the projection N, which is located on the part integral withthe driver E in a line with said tooth longitudinally of shaft C' andnear enough to the register-'wheel D when engaged by the tooth of driverE'to prevent sidewise disengagement until the tooth has passed out ofthe register-wheel and the periphery of driver E has locked theregister-wheel from rotation. Another provision secures the sameendnamely, the tooth 4r on leverH rides en the periphery of the shaftC', and thereby prevents the tooth g from disengaging with shaft Cat,all times except when the sockets of shaft C' is in positionto admitthe former tooth lr, which only occurs when the periphery of `the driverE, and not its tooth, is in the register-wheel D, and the tooth tlocksthe shaft Cf in position atall times when the tooth g is not entered inthe shaft C1ocking` that so that during counting the shaft-C islockedand the gears it'carries held in place for the count by tooth g, andduring restoration the shaft Cis locked bythey tooth fr, one shaft beingalways stationary.

' The intermediate gears F F'Fzlf3 F4 F5 are considerably wider than thegears G G G2 G i3 G4 G5, with which they engage, the excess ofv widthbeing on the left' of the latter in their positions shown in Figs. 1 and2, so that the moved enough to the right from their positions as shownin those gures to disengage the series of drivers E E' E2 Es E4 E5 EEfrom their respective register-wheels (since those-1 seen in Figs. l and2, forming the iuclines tt t2 s t4 t5 t6 wherever. on the periphery ofeach driver' itis intended to drawrthe register-wheel into gear with itafter separation for the process of restoration to zerob ut whichinclines v may Without much detriment intermediategears on the shaft Cmaybe pass entirely around the driver, and so may f b`e made cheaply'bybeing turned oif. These inclines may equally well be made on theregister-wheels by chamfering od the outer left. hand corner of eachthrough its periphery on thesidewherepit enters into engagement with itsdriver in the same manner as the driver is shown to be chamfered or maybe-made, as described, on both driver and register-Wheel.

Theyare rio 'IIS

not, of course, indispensab1e,'for that nicetyE Y may be used, or vifthe gears operate very. loosely Athey may bebrought together withoutthem; but the latter construction is objectionable and the formercostly'.

@ne of the advantages of using Geneva gear in this register is thefacility with which the driver and register-Wheel may be brought intogear together when the periphery' and not the tooth of the driver ispresented sidewise to enter engagement with the registerwheel, whichposition is the only one in which these parts are permitted to engageeach lab other, since the devices described prevent the driver E and theregister-wheel D from entering engagement eXcept in that position,

united register andintermediate wheels to rotation by friction of theshaft-C rotating in them to hold themfromaccidental misplace nicnt'uhenthe register-wheel 'and its driver are ungeared for restoration to zeroand prevent. their overrotat-ion.' Since the registerwheel D is attachedto no intermediate gear,-

. a like spring it is made to bear directly upon it. for like purposes,which is unohjectionable in counting owing to the very rare use of thatwheel; but if it be desired that the device he springless when used forcounting'a projection like an intermediate gear might be at.

tachcd toits left side, asseen in Figs. 1 and 2,' as the-intermediatesare att-ached to the other register-wheels,when the friction-spring nmight be made and operate like the others. Each of thesefrictionsprin'gs is attached to the case, and they may all he fingers ofone comb-spring so attached. Each of them (except spring uf, which doesnot leave the periphery of registerlwheel D6) is like'the spring shownin the enlarged view, Fig. l0, having an inclined projection like theprojection 'v thereon and v5, (seen in Fig. 1,) which inclines serve toraise the springs up to bear on the intermediate gears on the shaft Cwhen those 'gear-wheels are pushed to the right,- as seen in Fig'. 5;passing ,under the inclines.

liorconvenience of manipulation a crank C is attached to shaft C and aprojection w to lever Il, which lever has a circular opening fir, whichwhen shaft C is locked in its counting position by tooth g coincideswith another like opening i/ in a projectionof the case, in whichposition the parts may b e locked by' apadlock by passing the. haspthrough these openings :v and y, which, since all the gears interlock,will prevent tamper- `irg with the count.

The process of restoration is as follows: The shaft C' is turned tillthe socket s will admit thetooth r, in which position the tooth iif thedriverE has passed out of its notch in the wheel D. 'lhen the level' His turned on its pivot. till the-tooth g passes out of shaft C, whichcannot occur till the tooth yr enters seen in Fig. G.

motion first drives thtl shaft-pins far enough to the right from theirposition seen in Fig. 2 so that if rotated they will engage the'wheel-pins, as seen in Fig. 5, when pin ns,

striking washer e in its slot, pushes the whole series of gears on theshaft C, moving thc socket s in shaft C'. Shaft C is then .pushed intoits position seen in Fig. 5. This them, with the shaft, till theprojection e7 brings up against the case, which has a projection ltoreceive it, when the series is confined between the pin ne and thisprojection and the several gear-wheels on the shaft C have been pushedso far to the right from their position seen in Fig. 2 (the gears on theshaft C remaining stationary) that all the register wheels are ungearedfrom their drivers, (and can he rotated independently of them,) but notso far as to ungear the intermediate wheels. The same sidewisc motion tothe right projects the intermediate wheels v on the shaft l against theinclnes t' v, dac., ofthe springsit il. (which are held from side- Wisemotion by attachment to the case) and, lifts the springs till they bearon the tops of the intermediate wheels, resisting hy friction therotation of these and the register-wheels. Spring 11,6 is not so lifted,but always bears on' the periphery ofwheel D, Shaft C is then rotatedtill its shaft-pins engage the several wheel-pins wherever they may findthem left in the process of countipgithe key M having been passedout ofthe slot q to permit this rotation) and until the key M has maderacomplete rotation, reaching again its position to enter the slot q. 'lhetwo series of pins are so adjusted relative to each other that thiscoinplete,i'otation of shaft C, which necessarily engages the wheel-pinswith every register-wheel, giving a common rotation to all, bringssimultaneously all the' zero-figures of those wheels into the line ofobservation-points at the instant when the key M has reached itsposition to enter the slot q. This key M has a hearing in rotation onthe outer-.face of projection I, which holds the various parts on shaftClin proper position during restoration to zeroby its action inconjunction with the pin f, which bears on the inside, and pinnf. Ofcourse the gears could be held in place by hand-pressure without key Mduring this process, but it is a con,- venient help; and a slightdrawing pressure on shaft. C during the process is of advantage,

For many purposes thc intermediate gear F may be considered a'siinplcprojection of wheel D. Thus in application of the spring u. or of meansto actua-te the wheel D -as,- for example, wheel-pin o-they may bereferred' to as applied to wheel D or a projection thereof when actuallyapplied to wheel F.

Il' it be desired to show the digits and ero more prominently than inthe depressions of the register-wheels, projections may he made besidethem in the places of the springs, and they may be marked on thefull-rounded peripheries of the projections in proper order,

sired. 'lhe location of the figures on the periphery of the Geneva-gearregister-wheels instead of on the side enables a closer arrangment` ofthe observation-sections and is eecle'd-by putting these gears on oneshaft. Itris supposed, unless otherwise indicated, that *aregister-Wheel, when the term is used, has shown on its surface,including by this term projections actuated by it and rotating with it,a series of the representationsrequired for representing numbersarranged with reference to the display at a given observation-section ofparticular examples ofthe sameatparticular portions of the rotation ofthe register-wheel, counting from a predetermined starting positionthereof` A Geneva-gear register-wheel when referred to in general termsis a'register-wheel which isactnated to bringits display-figures to theobservation-section or held, when disi playing a particular examplethereof, either directly or through intermediate gearing by a Genevadriver. Thus D is such a wheel directly actuated andheld; but il"drivers E' E2 E3 had the series of figures shown arranged on theirperipheries similarly but in reverse order to those on register-wheels DD' D2 and a line of observation-openings be located. across their facesou the front of the lower half of case B parallel th the line shown,each driver being arranged to show 0, at the line when 0 appears at theupper line on the registerwheel immediately actuating it, it is obvious-that' the count on wheels ll D' D2 would appear on: those drivers aswell, for Y Iby the Geneva d river E through intermediate gearing.

. flhe operation of ungearing the Genevagear wheels D and E and D' andE' andv leaving the intermediate gears F and G engaged obviously doesnot depend more upon the greaterwdth of the moving gear F relative tothe gear G than of the moving gears D and D' relative to theirrespective engaging gears E and E', but with the mode of separationshown upon the gear width on the gear moving toward the pointofdisengagement arranged in the direction from which it is moved', counting from the point-ofdisengagement-namely, the point ou the stationarygear wherein the sidewise motion the moving gear leaves engagemenlwith'it.l This, which maybe called disengagement width, is greaterin theintermediate gears I and G than inthe Geneva gears D and E or D'v andE'. Disengagemeut width, as the 'term is herein used, is the distanceone of a couplet of connectinggears must be moved relatively to theother to disconnect the couplet, not in any direction indefinitely, butin the direction which has been prearranged and in which means ofproducing such relative motion has been provided for. It obviouslydepends upon three elements-first, the projections of the gearsthemselves; second, the location of the gears, and, third, the directionof the relative motion.
